Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Domestic openings are OK but trans-Pacific openings of previous session take a step back; High noise from the central US and Gulf coast

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for August 27, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet. That includes stations using fake or pirated call signs. Please continue to be patient and let the FCC finish their processes. UPDATED: Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

The Gulf coast and central US were again focal points for noise generating storms.  It was a noisier night than the previous in North Texas and noise failed to subside by morning as in previous sessions.  There were many areas of the country that were storm-free but those areas may not have been noise-free.

12-hour North American lightning summary


Geomagnetic conditions ranged from quiet to elevated-quiet levels.   The Bz is pointing to the South this morning and solar wind velocities are averaging near 345 km/s.   DST values were variable but generally followed the centerline.  Elevated high-latitude absorption was reported.




Toby, VE7CNF, tried a fun experiment using a 24-foot tall vertical with an 8-foot top loading wire and just a few radials.  He applied about 20-watts of power to the antenna for approximately 75 mW EIRP overnight.  I hope he will repeat this experiment during the Winter when the band has settled down further and we have more darkness.  My early experiments with short verticals and low power yielded very good results during the Winter.  I do recognize that weather conditions in British Columbia in January may make these types of tests difficult.  Its good to see this kind of effort, however, and will probably be more of the rule rather than the exception on MF and LF under Part-97 rules.

VE7CNF 24-hour WSPR activity


John, WA3ETD / WG2XKA, indicates that he provided reports for nine WSPR stations and he received reports from 22 unique stations.  John adds that he experienced “No action into the NW, but ZF1EJ both ways for 1st time this season.”

Doug, K4LY / WH2XZO, reported that “Condition deteriorated a bit as the Hawaii and the western Canadian stations didn’t make it into the WH2XZO log last night. The 29 stations who decoded XZO and 11 decoded were slightly down from previous two nights.”

Rick, W7RNB / WI2XJQ, provided reports for six WSPR stations and he received reports from eighteen unique stations.

David, N1DAY / WI2XUF, reported that he “…was back to transmitting last night on 630M with a new antenna configuration.  I replaced my three element vertical portion of the Marconi Tee with a 6 element caged design.  It seems to be an improvement as I was spotted last night by a number of stations to the North East that WI2XQU and WH2XZO were getting that I have been missing,  I am sitting at the base of a large mountain that blocks me between 15-50 deg so that is going to be an ongoing challenge. Initial results on 40M and 20M seem to be promising too as I have installed a relay that allows switching of the inductor coil in/out of the circuit.  In total, I received 10 stations last night, and was decoded by 24 stations with most of the activity occurring before 04:00 UTC.”

Ernie, KC4SIT / WI2XQU, indicated that he was in a receive-only capacity through the session.  He provided reports for nine WSPR stations with  “the majority between 1000-1500 km with WH2XXP the most distant at 2748 km.”

Mike, WA3TTS, reported that he decoded nine WSPR stations overnight, including WH2XXP ZF1EJ, WG2XIQ, WG2XXM, WG2XKA, WI2XSV, WH2XZO, WI2XUF, VE3CIQ, and WH2XXC.

Dave, N4DB, reported that he decoded six WSPR stations.

Hideo, JH3XCU, submitted this link detailing DX -> JA decode totals and DX -> JA S/N peaks for the session, as reported on the Japanese language 472 kHz website.

Roger, VK4YB, received reports from JA1NQI-2, JA1NQI/2, JA3TVF, JH1INM, VE6JY, VE6XH, VE7BDQ, VE7SL, W7IUV, WE2XPQ and WI2XBQ. He shared two-way reports with WH2XCR and WH2XGP.  Roger also provided a number of comments for the session and his on-going antenna work:

“This session was always going to be an anticlimax after yesterday. Storms just off the coast of NSW put paid to hearing any East coast stations. Even Ken, WG2XXM, was decoded only once. My signal was decoded by the usual suspects, including the Alberta twins. I am transmitting only on the original Bottom Hat antenna. The second Bottom Hat is of the same dimensions as the original but is useless, except to the West. This makes no sense. Since I dropped the vertical portion of the NE beam to only 80ft, it is just a shadow of its former self. I must get this antenna back to the top of the tree by hook or by crook. I was working on the JA beam today but need more time to finish the repairs. The South beam is working well. I can barely hear the southern SSB stations on any other antenna, but on the South beam they are Q5, and yet the WSPR reports show little difference. Another mystery.

I am not yet ready for this season. I need more and better antennas, but the 450 watt Linear Amp is working well. I have a blower on the heat sink and it works so well that the heat sink is stone cold about one minute after the amplifier goes to standby. The blower is rather noisy but muffin fans can’t do the job.”

Ken, K5DNL / WG2XXM, provided reports for four WSPR stations and he was decoded by fifty unique stations including VK4YB, ZL2AFP, WH2XCR, ZF1EJ and eight Canadian stations.

Joe, NU6O / WI2XBQ, provided reports for seven WSPR stations including VK4YB and he received reports from seventeen unique stations including ZL2AFP.  Joe reported that he had received “…a total of 9 spots from ZL2AFP. Signal peaked 6-10db stronger 17 Min after his SS. I had no spots from VK4YB. I did hear YB 3 times starting at 10:50… My last spot of YB was 13:12, my SR was at 13:09”

Ward, K7PO / WH2XXP, received reports from 56 unique stations including VK2XGJ,  ZL2AFP, ZL2BCG, VK4YB, VK3WRE, VK5AKK and VK3ALZ.

Larry, W7IUV / WH2XGP, provided reports for ten WSPR stations and he received reports from 26 unique stations including ZL2AFP and ZL2BCG.  He shared two-way reports with VK4YB.   As W7IUV, Larry provided reports for ten WSPR stations including VK4YB.  Larry added that “It’s been a while since ZF1EJ heard me. Only 4 spots from VK4YB.  Condx good but not as good as previous night…15 spots from ZL2AFP, one spot from ZL2BCG, and one from ZF1EJ…Did not watch band but from reports, seems it was quite unsettled…High Lats seem to still be attenuated some.”

It was a noisy start to the session with storms to the North and South but I suspect that my primary noise source was the storms in the north central US.  As we continue in a transitional state for propagation, I opted to just operate WSPR during the session, making my first transmission at 0152z.  Reports began quickly as it was fully dark here and we have transitioned to the point where as long as noise is not too high, reports begin with darkness (as opposed to three hours after darkness, which it typical for late June / early July).  Band activity was very good but domestic propagation was better here than  on long haul paths.  I did not hear WH2XCR nor did I repeat low power reports in Oceania.  At the start of the session, I opted to listen West but at bedtime I switched back to listening with the short vertical.  I doubt that listening with the K9AY loop would have changed the situation for the better by morning.  It was a good night but different from the previous session.  My transmission report details can be viewed here and my reception report details can be viewed here.
